V zen of the United States of America, and a resident of EastRutherford, county of Bergen, and State of New Jersey, have inventedcertain new and-useful: Improvements in Seamin -Machines, of which thefollowing is a speci cation.

My invention relates generally to seaming machines for joining the headsor ends of cans to thebodies' of the same, and has more particularreference to double seaming machines.

The heads of cans or other containing vessels are variously formed, andmy machine, while capable of seaming the several styles known in theart, is especially designed to seam a can with a' certain style of head,a style produced by the exigencies of trade, as Wlll e understood. fromthe following. When ship ing cans to the acker, one head or end of t ecan is shippe separately. In

'- order to get a ti ht joint, it has been found useful to provi e theflange of the head, which generally is straight horizontally, with arubber ring or with a ring of paste or paint. During the shi ment abovereferred to, this ring is frequent y injured, and for that reason thesaid flange of the head is now usually turned down at its outer edge orburred so as to protect the rubber ring. To roperly seam a can with astyle of head of t is character requires. a three step operation, or theaction of three seaming members, one member of which consists of twoopposed conical deflecting rolls. In an application for Letters Patentof the United States iiled on the 9th day of January, 190$,Ser. No.138,346, I have shown a which the work to be acted upon is relativelystationary while the seamin members travel around the work. 'It 1sobvious that this principle can be applied to machines for seamingeither circu ar or irregular-shaped cans, and that furthermore the*machine can be operated either by hand or automatically.

In the present instance, I have shown a machine in whichirregular-shaped cans are acted upon and which is automatic, though theclaimsjshould not be construed as being limited to the said particularconstruction. It is desirable, however, when OPP ed conical deflectingrolls are used in connection with the seaming of non-circular orirregular shaped cans, that, in addition to the usual cam and roller forcausing the seaming rolls to follow the general contour of the can,there be provisions for justifyingthe position of the conical deflectingrolls at the points of irregularity so as to maintain the said conicaldeflecting rolls tangent to the work at the said points of irregularity.This improvement is claimed generally in the com anion application Ser.No. 186603, and is'c aimed specifically with relation to a structurewhen t e work holding means are stationary and the seaming memberstravel in the present application. The seaming rolls may of course be ofany suitable construction, though one of particular advantage is shownherein.

A further improvement resides in a positive knockout mechanism adaptedto be operated automatically with the completion of each can.

Other improvements will appear as the specification proceeds.

Fig. 21 is a vertical sectional view ofthe said modification.

1 represents a frame of a suitable construction for properly supportingthe various arts of the mechanism. Power is derived in any suitablewayas from the shaft 2 connected with the countershaft 3 as by means ofpulleys 4 and belts (not shown). The countershaft 3 carries a bevel gear5 engaging with the bevel gear 6 on the upright shaft 7 carrying therevolving head 8. Located inside of the shaft 7 is a spindle 9 carryingthe cam 10 and chuck 11.

The revolving head 8 carries the three seaming members 12, 13 and 14 resectively. As the second seaming member em odies all the new features ofconstruction, this will be described first, (and reference will then behad afterwards to the first and third members. It will be understoodthat a double motion has to be imparted to all three seaming members,viz: a motion parallel to the shape of the work to be acted upon and amotion toward and away from the said work to cause the said seamingmembers to properly engage with the said work and act upon the same andthereafter to withdraw from the same. In order to carry this intoeffect, the said seaming members are provided with a contour carrier 15pivot-ed on the head 8 in a suitable manner. Mounted upon the contourcarrier is a seaming carrier 16, which, in turn, carries the seamingtool. This arrangement could of course be reversed, and the contourcarrier be mounted upon the seaming carrier,'in which instance theseaming tool would be carried by the contour carrier; the only requisitebeing that the said seaming tool partakes of the motion of bothcarriers.

The contour carrier. 15 will conveniently take the form of an arm havingan extension 17 carrying the roller 18 adapted to travel in the cam 10carried by the chuck 11. As the head 8 revolves, the seaming memberswill be carried around with the same and will be caused to travel in anorbit around the work to be acted upon parallel with the contour of thesaid work. In the present instance where the work is square the cam 10will of course have a contour substantially identical with the contourof the can or work to be acted upon. If the can were round the cam l0would of course be in the shape of a circle. In other words the cam 10will always have the same contour as the work to be acted upon. with thework to be acted upon.

The seaming carrier 16 Wlll conveniently take the form of a bell cranklever and is bevel gear 6.

The cam 10 is of course stationary This seaming carrier carries theseaming tool which in the present instance are in the form of rolls thesecond member ha'ving two opposed conical deflecting rolls. Means areprovided for moving this seaming carrier toward and away from the workas follows: One end of the lever or seaming carrier 16 is connected withthe plunger 21 sliding in the tube or cylinder 22 and normally adaptedto hold the seamingtool in engagement with the work by means of thespring 23 or by other suitable means. Inside the contour carrier 15 is aspindle 24 carrying the pinion 25 at its upper end and the cam 26 at itslower end. This pinion 25 engages with the .gear 19 moving in unisonwith the gear 27 meshing with the gear 28 on the upright shaft 29, whichlatter carries a second gear 30 engaging with the gear 31, moving withthe Connected with the plunger 21 is a roller 32 with which the cam 26is adapted to engage to move the seaming carrier away from the Work.This construction is common to all three seaming members; the seamingcarrier on the first .and second seaming member carrying the crimping orcurling roll 33 and finishing roll 34 respectively, while the secondseaming member carries two opposed conical deflecting rolls 35 and 36respectively.

The foregoing describes the construction of the first and third seamingmembers. The second seaming member, however, must, in addition to theabove means, be provided with mechanism for moving the two opposedconical deflecting rolls toward and away from each other at the propermoment and of irregularity for. maintaining the said opposed conicaldeflecting rolls tangent to the contour of the work at the said pointsof irregularity. These additional means will now be described. Pivot'edon the seaming carrier 16 is a straddling link 37 which carries thelower deflecting roll 36. 38 indicates a stud also mounted on theseaming carrier carrying a lower arm 39 adapted to engage with thestraddling link 37. Mounted on the said stud 38 is an upper arm 40'which bears upon the portion of the contour carrier 15. When the seamingcarrier moves in toward the work, the arm 40 'will engage with the contour carrier 15 thereby causing the arm 39 to move the straddling link37 and the roll 36 in an upward direction so as to move the said roll 36up against the upper conical deflecting roll 35.. Upon the returnmovement of the seaming carrier the reverse action will take place. Theseaming carrier is further provided with two justifying rollers 41 and42 mounted eccentrically one above the other and adapted to engage withthe superposed cams 43 and 44 on the chuck 11. These cams 43 and-44being of a shape substanpivoted at 20 on the contour carrier 15. tiallyparallel to the contour of the work to be acted upon, the saidjustifying rolls will always keep the said opposed conical defleetingrolls tangent to the work to be acted upon. In case of a non-circularcan, as in the present instance, it is obvious that on rounding a cornerthe deflecting rolls will project a distance in over the said cornerthereby causing an improper operation of the machine, having the resultof spoiling the can. It is therefore necessary to provide means or to soconstruct the parts comprising this second seaming member as to allowthe said deflecting rolls to recede slightly fromturning a corner. Inthe present instance, this means will take the form of projectingportions and 45 and 46 and 46 located on the corners of turning point ofthe said cams 43 and 44 or at other points of irregularity. The roll 41in rounding the corner will engage with the straight projection 45 andthen with the rounded projection 45 while the roll 42'will engage firstwith the rounded projection 46 and then with the straight projection 46.Of course it a circular can is to be seamed, these projections will bedispensed with.

The machine being in the present instance automatic throughout, anautomatic feed mechanism 47 is provided in this instance comprising: anintermittently rotatable disk 48 carrying a plurality of can supporters49. Suitable motion is imparted to this disk by means, the motion beingderived in the present instance from the shaft 29 through the worm 50 tothe gear-51 mounted on the shaft- 52, carrying at its other end a mitergear 53 engaging with the gear 54 mounted on tlie ipright shaft 55 andcarrying an arm 56 having a roller 57'adapted to engage with thetransversely slotted disk 58 mounted on the stud 59 and moving with thegear 60 which in turn engages with the gear 61 moving with the disk 48.This mechanism serves to bring the cans/tube seamed successively inalinement with the chuck 1]. Below the disk 48 and in alinement with thechuck 1 I there is provided, means for automatically elevating each cansupporter as it brought in alinement with the said chuck. This means maybe of any suitable construc tion; but in the present device takes theform of a plunger 62 adjustably on the sleeve 63 mounted on the stem 64by means of the lever 65 in a well known manner.

.The sleeve 63 carries the roll ,66 engaging with the cam 67 wherebyproper movement of the plunger 62 is effected to raise and lower thecan'su porters at the proper moment. Suitablb clamping means as 68 isalso provided for fastening the plunger 62 in the position to which ithas been adjusted. This device is well known in the art and need not bedescribed further.

It has been found advantageous to have positive mechanism for strippingthe can from the 'chuck 11. In the present instance this means takes theform of a spindle 69 extendin through the shaft 9 and through the chuck11 and having at its lower end the head 70 which forms art of the chuck11. This spindle 69 and ead 70 will normally be held in their uppermostpositions by means of the spring 71 attached to the pivoted link 72located at the up er end of the framework and attached witi one end tothe said spindle'69. At its other end, the said link 72 carries a roller73 engaging with the horizontal cam 74 which is conveniently mounted onthe shaft 55 although of course the motion could be obtained otherwise.

The cans being )laced upon the can sup-- porters 4!), the dis willrotate bringing the can into proper alinement with the chuck l1whereupon the said can supporter will be elevated so that the can comesin contact with the said chuck 11 by means previously described. The canwill be of a construction shown in Fig. 14 although it may be otherwiseformed; but as the present machine is more particularly adapted to seama can in which a rubber flange as 75 is inter posed between the end 76of the can and the body 77 of the same it is shown in the presentinstance. The disk 8 as it rotates, will bring the first seaming membercarrying the curling or crimping roll into juxtaposition with the can,the said seaming member traveling in an orbit parallel to' the contourof the can and moving gradually in toward the said can by reason of theconstruction previously described, and causing the crimping or curlingroll 33 to act upon the can producing the effect shown in F 1g. 15. Thesaid crimplng roll 33 remains in engagement with the can during severalrevolutions of the disk 8 after which it withdraws whereupon the twoopposed conical deflecting rolls are moved in toward the can producingthe effect shown in Fig. 16. In so doing, the lower conical deflectinroll 36 will move up toward the upper roll 35 the said roll being heldtangent to the contour of the work by the justifying means as theytravel in an orbit parallel to the contour of the can and recedeslightly on turning a corner. After the said opposed conical deflectingrolls have acted upon the can during several revolutions of the disk 8,they are withdrawn in the manner described and the finishing roll 34brought into contact with the can to flatten or finish the seam as shownin Fig. 17, the movement of the said roll 34 being substantiallyidentical to that of the roll 'lhe seam being new formed the can suporter will move down-and simultaneousy therewith the cam actuatedknockout will cause the said can to be stripped from the chuck 11whereupon another can will be moved into alinement with the chuck andelevating mechanism while the finished can is moved away by theautomatic feed mechanism.

It is of course obvious that the various parts are so ,timed as to causethe operation just described to take place in. the proper manner. Thewords Crimping and Curling used to denote the first of the three seamingtools is of course interchangeable and has merely reference to adiflerence in the construction of the said rolls and the claims shouldbe so construed. The finishng roll may finish the seam with either aflat or a rounded seam, as may be desired, in a well known manner.

In Figs. '19, 20 and 21 I have shown a modification of the secondseaming member.

In this instance, the contour carrier 78 merely serves to support theseaming carrier 79; the said seaming carrier being provided with twojustifying rolls 80 and 81 engaging with the cam 82 on the chuck 83, theroll 18 being dispensed with entirely in the present instance so thatthe two rolls 80 and 81 serve 4 both to cause the seaming member totravel in an orbitparallel to the contour.of the work to be acted uponand also serves to 'ustify the position of the opposed conicaldeflecting rolls 84 and 85 by maintaining them tangent to the contour ofthe'work. In this instance furthermore the stud 86 which rotates in thesame manner as the.

stud 24'carries the cam 87 adapted to rock the pivoted lever 88 theother end of which engages with the pushing pin 89 which in turnoperates a second pivoted lever- 90 which engages with a second pushingpin 91 which acts directly to move the lower deflectingroll 85 into andout of contact with the upper roll 84. I In this instance the deflectingrolls are caused to recede slightly in turning the corner by means ofthe cam 102 and roller 103.

In Fig. 18 1 have shown modification of the cam actuated knock-out. Inthis instance motion is imparted to the shaft 92 1 by means of the worm93 and worm gear 94.

Located upon the said shaft 92 is a cam 95. Mounted in the framework isa crank lever 96 caused to bear against the said cam 95 by means of thespring 97, the said spring further having the function of normallykeeping the spindle 98 which carries the knock-out in its uppermostposition through the instrumentality of a pivoted lever 99 andconnecting rod 100. As the cam 95 rotates, the raised surface 101 of thesame will engage with the crank lever 96 and raise the same therebydepressing the spindle 98. Various other means could of course be usedto effect the same movement.

Having thus described my invention, what I claim is: p
